What do you guys think ? which onw will give you more hp over all ?

 

The designs are similar so the amount of power gained should be similar. There are other things to consider when choosing between these headers. Cattman's fit much better, while HS's are less expensive, etc.

 

I will say that I am satistfied with the quality and performance increase of the hotshot headers. I don't think you are going to find many who have had both and can give you a good comparison. I would have liked to have sprung for the better quality and fit of the cattman, but I landed on a killer deal on my hotshots.

 

I am very happy with my HS headers
